  • 512 GB total capacity from four 128 GB modules maximises Supermicro H13SSH memory slots
  • DDR5 4800 speed with CL40 latency matches the board's rated timing for full-speed operation
  • Registered ECC design with 2Rx4 organisation offloads the memory controller and corrects single-bit errors
  • 1 V DDR5 voltage meets the platform's spec for stable, low-power server deployment
  • 288-pin RDIMM form factor is the exact physical and electrical fit for the H13SSH motherboard

Exact-match upgrade kit

This 512GB kit delivers four 128GB DDR5 4800 RDIMMs built to the Supermicro H13SSH memory controller's exact rank, voltage and timing requirements. Registered ECC architecture with CL40 latency and 1.1V operation ensures the modules are recognised at full capacity and run at rated speed without manual tuning.

Sustained-load behaviour

Registered buffering offloads the memory controller so every slot remains stable when fully populated, while on-die ECC corrects single-bit errors in real time to prevent silent data corruption during continuous workloads. The 2Rx4 organisation maintains signal integrity across all four modules under prolonged utilisation.

DDR5 interface limits

DDR5 4800 (PC5-38400) sets the maximum transfer rate this kit can achieve on the platform. Population rules, maximum supported capacity per slot and approved DIMM order are defined by the motherboard manual and must be verified before installation to avoid configuration conflicts.

Questions about this item

How much power do the 1.1 V DDR5 4800 modules draw when the server runs continuously?

Each module operates at 1.10 V. Total system power depends on the Supermicro H13SSH motherboard and CPU load; the kit itself adds four registered DDR5 DIMMs at the rated voltage.

What motherboard slot type is required for this 288-pin RDIMM kit?

The Supermicro H13SSH must provide DDR5 288-pin RDIMM slots. The kit will not fit UDIMM or SODIMM sockets, and the board must support registered ECC memory.

Can I mix these 2Rx4 CL40 DDR5 RDIMMs with other DDR5 registered modules already installed in the H13SSH?

Mixing is possible only if the other modules are also DDR5 registered ECC RDIMMs with matching voltage and timing; the H13SSH memory population rules must be followed for full capacity recognition.
